HANDLE-FASTEN ER.

SPECIFICATION forming part of Letters Patent-No. 746,086, dated December8, 1903.

- Application filed April 18, 1903.

To all whom, it may concern;

Be it known that we, RICHARD S. HOYT, HENRY P. HOYT, and ERNEST C. HOYT,citizens of the United States, residing at Fortside elevation of ourappliance detached.

cam-face 13.

Fig. 5 is a top plan view of the appliance. Fig. 6 is a sectional viewon the line 6 6, Fig. 5, looking in the direction of the arrows.

7 represents an ax, shown for purpose of illustration, and 8 is a handleof any approved style therefor, both being broken away, the

handle bein'g in the usual opening through the ax provided for thatpurpose.

9 is a recess formed in the ax and com munieating with thehandle-opening referred to,the

rear wall of which is parallel with the buttend of the ax, while the topwall, as well as the bottom wall, of the recess is formed on an obliqueangle, as more clearly shown in Fig.- -3.

10 is an opening formed in the ax and leading upward from the bottomthereof into the recess 9 and provided with suitable screwthreads to behereinafter referred to.

11 is acrescent-shaped plate having a curvature on its under. side likethat of a toolhandle, as best seen in Fig 9. This plate is equal inlength to the height of the tool for which it is adapted and is of asuitable material.

12 is a lug integral with and extending from the base-plate 11 and isprovided witha Said lug. isv provided near its upper end with' acam-slot 14, extending in a direction transverse of the base-plate l1.

15 is a screw passing through the'ax and through the cam-slot 14,whereby the plate 11 and its lug are held against displacement and atthe same time guided in their movement.

Serial lilo. 153,250. (No model.)

adapted to enter the opening 19, the threads thereof intermeshing withthe thread of the said opening.

17 is a rectangular screw 16. This screw 16 is provided with a conicalpoint 18, the cone being on the same angle as that of theicam-face'13 ofthe lug 12, with which it coacts, as will be fully herein- ,afterpointed out.

The parts being assembled in the position shown in Fig. 3, a wrench orother suit-able tool is applied. to the'screw 16, whereupon it isrevolved and working upon the threads of the opening 10 it is advanced.In advancing of the. lug 12, whereupon by its continued advancement theplate 11 is crowded toward and against the handle of the tool, thuswedging or locking the handle in the tool or ax 9 facilitates themovement of the lug 12 and plate 11, as does also the cam-slot 14 andthe face of the lugin proper relative position with the conical point 18of the-screw 16, as will be understood by all mechanics.

Any desired pressure may be applied by the continued turning of thescrew 16.

Should the handle become loose by reason only necessary to give theset-screw 16 several'turns to again tightly clamp the handle in .ax orother tool.

The top ofthe lug 12 is beveled to adapt it to slide readily on'the topwall of the recess.

It will be thus seen that we have provided a cheap, simple, bute'ifective clamp for the purpose set forth.

What we claim,.and desire to secure by Letters Patent, is-

1. The combination with a tool-head, of a locking-plate placed inthe'eye thereof, so that one edge may engage thehandle and the otheredge presenting an incline, a screw passing through the head andengagingthe said incline and thereby forcing the plate laterally againstsaid handle.

2. The combination with a tool-head, of a locking-plate placed in theeye thereof, so that 16 is a combined set and locking serew headintegral with the its conical point 18 engages the cam-face 13' 7 head.vThe angle of the top wall of the recess screw 15, by guiding it andkeeping the camof shrinkage or for any other reason, it is one edgemayengage the handle and the other names to this specification inresence of two to edge presenting an incline, a screw passing witnesses.

through the head and engaging the said ineline and thereby forcing theplate laterally 5 against said handle, a pin engaging a transverse slotin the plate to retain it in the head while permitting sneh lateralmovement of RICHARD S. HOYT.
